Bch Wallet Client

The official client library for bch-wallet-service.

Attribution

This repository was created by copy forking bitcore-wallet-client commit d986bbb.

Description

This package communicates with BCHWS Bch wallet service using the REST API. All REST endpoints are wrapped as simple async methods. All relevant responses from BCHWS are checked independently by the peers, thus the importance of using this library when talking to a third party BCHWS instance.

See Bch-wallet for a simple CLI wallet implementation that relays on BCHWS and uses bch-wallet-client.

Get Started

You can start using bch-wallet-client in any of these two ways:

via Bower: by running bower install bch-wallet-client from your console
or via NPM: by running npm install bch-wallet-client from your console.

Example

Start your own local Bch wallet service instance. In this example we assume you have bch-wallet-service running on your localhost:3232.

Then create two files irene.js and tomas.js with the content below:

irene.js

var Client = require('@owstack/bch-wallet-client');


var fs = require('fs');
var BCHWS_INSTANCE_URL = 'https://bchws.openwalletstack.com/bchws/api'

var client = new Client({
  baseUrl: BCHWS_INSTANCE_URL,
  verbose: false,
});

client.createWallet("My Wallet", "Irene", 2, 2, {network: 'testnet'}, function(err, secret) {
  if (err) {
    console.log('error: ',err); 
    return
  };
  // Handle err
  console.log('Wallet Created. Share this secret with your copayers: ' + secret);
  fs.writeFileSync('irene.dat', client.export());
});

tomas.js

var Client = require('@owstack/bch-wallet-client');


var fs = require('fs');
var BCHWS_INSTANCE_URL = 'https://bchws.openwalletstack.com/bchws/api'

var secret = process.argv[2];
if (!secret) {
  console.log('./tomas.js <Secret>')

  process.exit(0);
}

var client = new Client({
  baseUrl: BCHWS_INSTANCE_URL,
  verbose: false,
});

client.joinWallet(secret, "Tomas", {}, function(err, wallet) {
  if (err) {
    console.log('error: ', err);
    return
  };

  console.log('Joined ' + wallet.name + '!');
  fs.writeFileSync('tomas.dat', client.export());


  client.openWallet(function(err, ret) {
    if (err) {
      console.log('error: ', err);
      return
    };
    console.log('\n\n** Wallet Info', ret); //TODO

    console.log('\n\nCreating first address:', ret); //TODO
    if (ret.wallet.status == 'complete') {
      client.createAddress({}, function(err,addr){
        if (err) {
          console.log('error: ', err);
          return;
        };

        console.log('\nReturn:', addr)
      });
    }
  });
});

Install bch-wallet-client before start:

npm i bch-wallet-client

Create a new wallet with the first script:

$ node irene.js
info Generating new keys 
 Wallet Created. Share this secret with your copayers: JbTDjtUkvWS4c3mgAtJf4zKyRGzdQzZacfx2S7gRqPLcbeAWaSDEnazFJF6mKbzBvY1ZRwZCbvT

Join to this wallet with generated secret:

$ node tomas.js JbTDjtUkvWS4c3mgAtJf4zKyRGzdQzZacfx2S7gRqPLcbeAWaSDEnazFJF6mKbzBvY1ZRwZCbvT
Joined My Wallet!

Wallet Info: [...]

Creating first address:

Return: [...]

Note that the scripts created two files named irene.dat and tomas.dat. With these files you can get status, generate addresses, create proposals, sign transactions, etc.
